LONDON-A British judge on Thursday sentenced a businessman who sold fake(假冒的) bomb detectors（探测器） to 10 years in prison, saying the man hadn't cared about potentially deadly consequences.

    It is believed that James McCormick got about $77.8 million from the sales of his detectors-which were based on a kind of golf ball finder--to countries including Iraq, Belgium and Saudi Arabia.

    McCormick, 57, was convicted(判罪) of cheats last month and sentenced Thursday at the Old Bailey court in London.

    “Your cheating conduct in selling a great amount of useless equipment simply for huge profit promoted a false sense of security and in all probability materially contributed to causing death and injury to innocent people,” Judge Richard Hone told McCormick. “you have neither regret, nor shame, nor any sense of guilt.”

    The detectors, sold for up to $42,000 each, were said to be able to find such dangerous objects as bombs under water and from the air. But in fact they “lacked any grounding in science” and were of no use.

    McCormick had told the court that he sold his detectors to the police in Kenya, the prison service in Hong Kong, the army in Egypt and the border control in Thailand.

    “I never had any bad results from customers,” he said

    One day an old woman was travelling alone in the mountains. Suddenly she saw something shining in the stream（溪流）. When she came close, she found it was a precious（宝贵的）stone. She put the stone into her bag and went on with her trip.

    The next day the old woman met a young man, who was also a traveler in the mountains. The young man looked very hungry, so the old woman opened her bag to share her food. The hungry traveler saw the precious stone and asked carefully, "The stone is beautiful. Would you like to give it to me?"

    "Sure. Why not?" the woman said, and handed the stone to him.

    The young man left happily with the stone. He knew it was worth enough to give him security for a lifetime. But a few days later he came back to return the stone to the woman.

    "I've been thinking." he said. "I know how valuable the stone is, but I give it back and hope that you can give me something even more precious. Give me what you have in your bag."

    The woman opened her bag. It was almost empty. She looked at the young man and smiled, "I have nothing special in my bag, but I do have something precious—the joy of giving!"

    The young man felt ashamed (惭愧的）and left silently.

    Scientists think that growing garden grass could be the secret to solving our energy needs, and we may soon be able to replace our gasoline with "grassoline".

    The team, including experts from Cardiff University in Wales, has shown that hydrogen can be taken from grass in useful amounts with the help of sunlight and a cheap catalyst(催化剂) —something that speeds up a chemical reaction without being used up.

    It is the first time that this has been shown and it could lead to a sustainable(可持续的) way of making hydrogen, reported Asian News International. This could be an important kind of renewable energy because it is high in energy and it does not give out harmful gases when it is burned.

    Study co-author Michael Bowker said, "This is really a green source of energy. Hydrogen is seen as an important future energy carrier as the world moves from fossil fuels to renewable energy, and our research has shown that even garden grass could be a good way of getting it."

    Cellulose(纤维素), which is a key part of plants and the biopolymer(生物聚合物) found in the largest numbers on the earth, could be a great source of hydrogen.

In its study, the team looked at the possibility of getting hydrogen from cellulose using sunlight and a simple catalyst.

    This is called photocatalysis(光催化作用) and in it, the sunlight starts the catalyst, which then makes cellulose and water into hydrogen. The researchers studied the effectiveness of three metal-based catalysts, of which nickel(镍) especially interested the researchers, as it is a much more common metal than gold and palladium(钯) and it saves more money.

    According to Bowker, producing hydrogen from cellulose using photocatalysis has not been studied in detail. The team's research shows that large amounts of hydrogen can be produced using this method with the help of a bit of sunlight and a cheap catalyst.

    The study shows that it is effective to use real grass taken from a garden. "This is important as it avoids the need to separate and clean up cellulose, which can be both difficult and costly," said Bowker.

    New study shows that when teachers participate in a training program focused on prosocial (亲社会的) classroom behavior, their students are better able to control their emotions, and that children who can regulate emotions are more likely to be academically successful.

    For the study, which appears in Prevention Science, researchers looked at more than 100 teachers and 1,817 students from kindergarten to third grade to see if teachers could support students' emotional and behavioral growth through the Incredible Years Teacher Classroom Management (IYTCM) program.

    The program uses videos and training sessions, along with role-playing and coaching, to help teachers learn management skills such as using behavior-specific praise, building positive relationships with students, and considering how to reduce poor behavior. Teachers in the training group increased interactions with students by 64 percent compared with 53 percent for teachers in the control group without the training.

    "Emotional regulation is the ability to recognize what behavior is appropriate in the present situation," says Wendy Reinke, professor in the College of Education at the University of Missouri. "For example, a student might have difficulty controlling the feeling of anger if he or she becomes annoyed with another student. But under this program, the teacher encourages them to move to a different spot in the classroom, effectively teaching them that sometimes stepping away and taking a break is a good way to calm down and manage8ha8feeling."

    After one school year of using the program in classrooms, students improved their social ability and ability to regulate their emotions. These improvements resulted in an increase in the tests for students in Incredible Years classrooms vs. students in control classrooms. And this classroom management approach can help reduce the risk for struggling learners early on, which could help prevent more accumulative support needs in a child's future.

    It's holiday season and time for shopping. There are a bunch of items on your shopping lists ranging from small gifts, toys and festive decorations to Christmas and New Year cards. What's your first reaction to products labeled "Made in China"? If you still tend to relate "Made in China" to poor quality, you need to update your ideas. China's ability to produce high-quality products has been recognized by a growing number of foreigners. It's a misunderstanding to associate low quality with "Made in China".

    Cameron Purdy, a Web user, says that China manufactures poor-quality products does not mean it cannot manufacture high-quality products. He explains that the poor-quality products one purchases in the US for example, are made in the quality that the American companies ask for. "The price that you pay for the product has no relationship to the cost of its manufacturing," suggested Purdy. For example, for an item priced at $20 in the US, the cost of manufacturing it paid by the American company is usually less than $1. To guarantee the room for profit, the Chinese co-manufacturer spends less than $1 to produce the item.

    Amanda Wu, who lives in Shanghai, noted that many top brands have manufacturing factories located in China, and the most convincing example of China's manufacturing quality is Apple products. On the back of the iPhone, one can find the product is Made in China—"Designed by Apple in California. Assembled (装备) in China. "Chinese and foreign Web users commented that some Chinese products with good reputations around the world are Haier, Lenovo, GREE, Huawei and China Railway High-speed.

    On the other hand, foreign misunderstandings can sometimes affect Chinese people's minds. For instance, when Chinese people travel abroad, some would still avoid buying products Made in China. It's time for the world to stop relating Made in China with low-quality products. Just remember, you get what you pay for.

Whether in the home or the workplace, social robots are going to become a lot more common in the next few years. Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.

While household robots today do the normal housework, social robots will be much more like companions than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.

The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn't just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.

Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.

Fellow Robots is one company bringing social robots to the market. The company's "Oshbot" robot is built to assist customers in a store, which can help the customers find items and help guide them to the product's location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.

The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees." We have technologies to train social robots to do things not for us, but with us," said Breazeal.
